Black buttons that only show text "Fancy Buttons"

[mikeslinkman]

When I add and design a fancy button in my layout file the result that is outputted seems correct. Like the image in this link. However when I build the app to my phone the exact same button looks like the image shown in this link

The button displayed here looks like the following in XML:

    <mehdi.sakout.fancybuttons.FancyButton
        android:id="@+id/btn_login"
        android:layout_width="0dp"
        android:layout_height="0dp"
        app:layout_constraintBottom_toTopOf="@+id/end_middle_button"
        app:layout_constraintEnd_toStartOf="@+id/end_button_width"
        app:layout_constraintStart_toStartOf="@+id/start_button_width"
        app:layout_constraintTop_toTopOf="@+id/start_middle_button"
        fancy:fb_borderColor="#FFFFFF"
        fancy:fb_borderWidth="1dp"
        fancy:fb_defaultColor="#FFFFFF"
        fancy:fb_focusColor="#EEF2F5"
        fancy:fb_radius="30dp"
        fancy:fb_text="LOGIN"
        fancy:fb_textColor="#000000"
        fancy:fb_textSize="18sp">
    </mehdi.sakout.fancybuttons.FancyButton>
